What is it?

LFM3-1.7B is a text-only language model in the Liquid Foundation Model family, intended for local agents, tool calling, structured outputs, and domain-specific fine-tuning.

How does it work?

It uses a tri-hybrid layer mix of 13 gated short convolutions, 5 sliding-window attention layers, and 6 global attention layers across 24 layers; the model was post-trained on agentic traces and tool calls and can run at 4-bit precision using about 1 GB of memory.

How well does it do?

On the Claw-Eval General (EN) benchmark it scores an average of 68.64, and on the ToolSandbox benchmark it reaches 80.36; for coding it attains 73.46 on LiveCodeBench v6, and for instruction following it gets 96.66 on IFEval.

What does it need to run?

At 4-bit precision the model fits in roughly 1 GB of memory, allowing inference on phones, laptops, or any GPU-enabled device; supported inference frameworks include vLLM, SGLang, llama.cpp, MLX, and ONNX.

By the numbers

The honest read

The reported benchmark numbers come from the model card and reflect the authors' own evaluations; they do not include comparisons to other labs' models beyond the table shown. Scores such as the 68.64 on Claw-Eval and 80.36 on ToolSandbox demonstrate capability on specific agentic and tool-use tasks, but the model card notes it is not recommended for complex multi-step reasoning or agentic coding due to its small size. The memory claim of "about 1 GB" applies only when the model is quantized to 4-bit precision; larger precisions would require more RAM. Performance figures are limited to the listed benchmarks and do not cover latency, power consumption, or real-world user experience, so they give an incomplete picture of deployment suitability.
